The present invention is a modular deck system with height adjustable leg assemblies. The deck modules each have a top panel, a support frame, and a leg receptacle. The leg assemblies include a base foot, an adjustment bolt and a leg bracket with four legs extending perpendicularly from a bracket plate. A height adjustment bolt is fixed to the base of the leg assembly and extends perpendicularly from the base through an aperture in the bracket plate. The deck modules are placed adjacent to each other, side-by-side and end-to-end in the desired layout, then secured with the leg assemblies. Leveling of the deck modules is achieved through rotation of the adjustment bolts.

A bicycle transmission is configured and arranged to improve the durability of the transmission. The transmission basically has a transmission operating device, a support structure, a front input section, an intermediate transmission and a rear output section. The transmission operating device operates the intermediate transmission to change the gear ratio between the front input section and the rear output section. The intermediate transmission has a plurality of drive members arranged to move in the axial direction on an intermediate drive axle in response to its pivotal movement shifting structure. An endless drive member is operatively coupled between a rotatable driving member of the front input section and one of the intermediate drive members. The endless drive member remains substantially in a single plane during shifting of the drive members on the intermediate drive axle.

The invention relates to an anti-collision beam, more specifically to a truck energy absorbing anti-collision beam. The truck energy absorbing anti-collision beam comprises a fixing connecting frame,an anti-collision seat, an anti-collision beam, side anti-collision pieces and a linkage device. According to the truck energy absorbing anti-collision beam, the width of the anti-collision beam in anormal state is adaptive to that of a truck; when a low vehicle collides with the anti-collision beam, the anti-collision beam can absorb energy; and moreover, when the anti-collision beam suffers collision, the two side anti-collision pieces can stretch to widen the anti-collision beam so as to improve the protecting effect of the anti-collision beam. According to the truck energy absorbing anti-collision beam, the anti-collision beam can be lifted to avoid a situation that an excavator is not prone to approaching during loading goods due to too small ground clearance of the anti-collision beam. The anti-collision seat can vertically slide on the fixing connecting frame; the anti-collision beam can slide on the anti-collision seat from front to back; and the two side anti-collision piecesare slidingly connected to the left and right ends of the anti-collision seat.

A crankcase is provided therein with an oil suction passage makes an oil pump and an end part of a bottom wall of an oil sump chamber communicate with each other, passes between the oil sump chamber and a hanger boss, and has a lowest part located below the bottom wall of the oil sump chamber.

The invention relates to a motor vehicle, in particular an off-road vehicle or a pick-up truck, with an underguard (2) having a crash plate (16) mounted on the underside of the motor vehicle superior. To create an improved underguard, the impact panel (16) is movably mounted on the bottom surface between a stowed position and a deployed position.

The invention provides an energy absorbing type rear protection device capable of automatically adjusting height. The energy absorbing type rear protection device capable of automatically adjusting the height comprises two ground clearance detection mechanisms, two 4-shaped brackets, a transmission mechanism, B-shaped cross beams and energy absorbing units; the two 4-shaped brackets are symmetrically mounted on the external side surfaces of two longitudinal beams at the tail part of a commercial vehicle; the two 4-shaped brackets are connected with each other through the transmission mechanism; the B-shaped cross beams are connected to the end surfaces, facing the vehicle tail, of the 4-shaped brackets through the energy absorbing units; the two ground clearance detection mechanisms are correspondingly connected to the internal sides of the two longitudinal beams at the tail part of the commercial vehicle through connecting pins; each ground clearance detection mechanism comprises a connecting head, a connecting rod and a plate with a universal wheel; the connecting heads are mounted on the internal sides of the longitudinal beams at the tail part of the commercial vehicle throughconnecting pins; and the connecting heads can rotate around the connecting pins. According to the energy absorbing type rear protection device capable of automatically adjusting the height, the obstacle crossing ability is realized, collision energy can be stably absorbed stage by stage, the rigidity in the height direction is distributed in a graded manner, and an automobile suffering rear-end collision can be effectively prevented from getting to the bottom of a truck.

An active front splitter for automobile is movably connected to a splitter support by a spindle support at each of its two ends. A driving mechanism being mounted to the splitter support at each of its two ends, an electric motor being mounted in the middle of the splitter support. The driving mechanism is driven by the electric motor and fixedly connected with the active front splitter so that the active front splitter is driven by the driving mechanism to rotate around a spindle fixed to the splitter support between a forwardly extended position and a retreated position. Thus, while ensuring the trafficability of the assembled automobile, it is possible to reduce wind drag so that the expected aerodynamic performance can be achieved.
